SPECIFICATION forming' part Of LBtterS Patent NO. 704,597, dated July 15, 1902.

Application filed March 10,1902. Serial No. 97,561. (No model.)

To all whom, it 717,553/ Concern:

Be it known that I, PETER G. TOEPFER, a citizen ofthe United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Malt-Kilns and I do hereby declare that the following is a full, clear, and exact description thereof.

The improvements consist in certain peculiarities of construction and combination of parts hereinafter particularly set forth with reference to the accompanying dra-wings and subsequently claimed, the object of the invention being to furnish simple, economical dump-tray malt-kiln floors and provide for dropping sections of the same to lower than normal level preliminary to a dumping operation, this dropping of the floorsections being done to obtain necessary clearance for the trays under machinery or nicheplates in a kiln.

Figure l of the drawings herewith represents a transverse section through a portion of a dumpstray malt-kiln floor to which my improvements are applied, this view being indicated by line 1 l in the fourth figure of the series and having the dropped and dump positions of trays illustrated therein by dotted lines; Fig. 2, a horizontal section longitudinally of the kiln, as indicated by lines 2 2 in said fourth figure, the movable parts in the view being in the position to which they are adjusted when the trays are-dumped; Fig. 3, a plan view, partly in horizontal section, through walls of the kiln; and Fig. 4, a longitudinal section view indicatedby lines It et in the first figure. V

Referring by letter to the drawings, A indicates an end wall, and B a side wall, of a malt-kiln having a dump-tray floor. Like in my Patent No. 588,507, issued August 17, 1897, the arrangement of the perforated ioorplates of the dumping-trays is such that each of said plates laps the tray-frame next adjacent to its own in successive order transversely of the kiln, whereby a flush iioor is obtained when the trays are horizontal.

The preferably angular tray-shafts C are provided with rigid journal-collars D, herein shown engaging elongated bearing-apertures vertically of kiln-wall plates E, and link-connected cranks F are shown as having rounded J are shown as having their branches in piv' otal connection with kiln-wall brackets K and hangers L, these hangers being rigid with the braces I aforesaid. The transverse portions of the levers J oppose under edges of tray-frames in a section of the kiln-floor, and alink-bar M is coupled to said transverse portions of the levers. A depending bracket N of the link-bar is coupled to links P, that extend through a kiln-wall aperture and conneet with a hand-lever Q, for which a fulcrum-standard R is provided. A latch S is shown conveniently arranged to be swung over one of the links P and lock the trays in horizontal position at their greatest elevation, the side trays being then snug under niche-plates in kilns provided with travel ing rotary malt-stirrers, such a plate T being shown in Fig. 3. The latch S being swung, away from engagement with the adjacent link P, the hand-lever Q is operated to move the link-bar M and leversJ from position shown by full lines in Fig. 4 toward that shown by dotted lines in the same iig ure, all the trays in a Hoor-section above the barconnected levers being thus bodily lowered in horizontal position until the journalcollars D'and crank `bosses Z1' on the trayshafts come into bearing contact with the lower extremities of the apertures in kilnwall plates E E', the other collars G on said shafts being then at rest in the upper bearing-seats of the brackets H, whereby there is sufficient clearance of any adjacent stirrer or niche-plates to` permit dumping tilt of said trays. Continued lowering of the bar-connected levers J will ordinarily result in an immediate tilt dump of the adjacent trays by gravity g' but should said trays stick from any cause thecranks F may be actuated to overcome the resistance. The levers J being lifted, the dump-trays of a kiln-Hoor section IOO lzo

are restored to normal position and held therein by means of the latch S, swung into working position, as aforesaid. i f

While I have provided for a lowering of malt-kiln-lloor. sections to obtain tray clearance of machinery, niche plates, or both, such provision is not necessary in all kilns. Hence the bearing-apertures in plates E E may be full round instead of elongated and the brackets H sufficiently elevated to have the bearing-seats of same in permanent contact with the collars G on the tray-shafts, dumping tilt of the trays taking place when the bar-connected levers .I are swung down.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A malt-kiln iioor comprising tilt-dump trays, levers having transverse portions opposing under edges of frames constituting parts of the trays, a link-bar connecting the levers, and means for actuating` the link-bar.

2. A malt-kiln floor comprising tilt-dump trays having shafts provided with journalcollars engaging vertically-elongated bearings, other collars rigid on the tray-shafts at intervals of the same, bearing-bracketsstationary under the latter collars normally clear of the same, levers having transverse portions opposing under edges of frames constitnting parts of the trays, a link-bar connecting the levers, and means for actuating the link-bar.

3. A malt-kiln iioor comprisingtilt-dump trays, levers having transverse portions opposing under edges of frames constituting parts of the trays, a link-bar connecting the levers, a bracket depending from the link- 1car, a hand-lever in link connection with the bracket, and means for locking the trays in horizontal position.

4. A malt-kiln floor comprising tilt-dump trays having shafts provided with journalcollars and rounded end bosses of link-connected cranks engaging vertically-elongated bearings, other collars rigid on the tray-shafts at intervals of the same, bearing-brackets stationary under the latter collars normally clear of the same, levershaving transverse portions opposing under edges of the frames constituting parts of the trays, a link-bar cona necting the levers, and means for actuating the link-bar.

5. A malt-kiln lioor comprising tilt-dump trays vertically adjustable in horizontal position to be dropped from their normal level preliminary to dumping operation so as to avoid obstructions.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county o f Milwaukee and State of Wisconsin, in thc presence of two witnesses.
